A sensitive chalcogenide-based electrochemical sensor for ultra-level detection of Mospilan residues in real samples

Year: 2025

Type: article

Abstract: Addressed herein, the synthetic bismuthinite and bismuthinite@copper sulphide as two metal chalcogenides have been applied for modifying a glassy carbon electrode(GCE). The as-prepared nanomaterials were characterized using X-ray diffraction (XRD), scanning electron microscopy(SEM) and Energy-dispersive X-ray spectroscopy(EDX). By comparing the results, bismuthinite @copper sulphide hybridized with graphene oxide (GO) modified electrode exhibited superior sensitivity for detection ultra-levels of pesticide Mospilan (acetamiprid) in real samples. The dynamic concentration range of acetamiprid was found to be 80-680nM with a remarkably low detection limit about 4.1nM along with good stability and repeatability. Finally, the fabricated electrochemical sensor, bismuthinite@copper sulphide/GO, was suggested as a suitable alternative to more complex enzyme-based and aptamer-based methods for Mospilan detection.
